- There are many axioms in sport that are taken at face value. One of them is that the playoffs are somehow totally different from the regular season. The aim of this study was to test that axiom by comparing in-game statistics during the regular season and the playoffs in the semi-professional Icelandic elite men’s handball league. Data from 724 games (648 regular season games and 76 playoff games; 1448 data points) across five seasons were analysed using a two-level logistic regression analysis. The variables of interest were pace, fast breaks, legal stops, penalty throws given, 2-minute suspensions, and saves. The results indicated no meaningful differences in fast breaks, penalty throws given or number of saves, but did find signs of added intensity during the playoffs with a higher pace, more legal stops and more 2-minute suspensions. While the differences were not particularly large, they have the possibility of being practically meaningful and were in line with the axiom. Possible explanations were discussed but more research is needed to determine whether these findings are context- or sport-specific. © 2022 The Author(s).

- Indications of laterall biases favouring left-handers have been found in various sports; especially interactive sports where the athletes have limited time to react to incoming objects. The aim of this study was therefore to explore whether any lateral biases exist in handball by examining 7-meter shots. A total of 6846 7-meter throws from 240 7-meter shooters across four seasons in the semi-professional Icelandic elite handball division (male and female) were analyzed. Out of the 240 7-meter shooters, of which 151 were male and 89 were female, 22% were left-handed (22% of the males and 20% of the females). The left-handed 7-meter shooters took a disproportionate number of the 7-meter shots, with left-handed shooters performing 29% of the 7-meter shots (27% in the male league and 33% in the female league). The results of a Bayesian two-level analysis indicated that left-handedness is not associated with greater success from the 7-meter line at the semi-professional level. © 2023 The Author(s).

- An asymmetry in the prevalence of left-handedness vs. right-handedness in society has supposedly resulted in negative frequency-dependent advantages for left-handers in interactive sports. The aim of this study was to test whether these advantages apply to handball by examining whether being left-handed is beneficial when executing 7 m shots, a highly unimanual movement. All 1,625 7 m shots at the men’s 2016–2022 European championships were analyzed using a Bayesian two-level analysis. While the results did not indicate that left-handers were more likely to score from any single 7 m shot, left-handers were overrepresented among the designated shooters compared to both the population as a whole (38% vs. 11.6%) and left-handers on any given handball team (38% vs. 25%). The implication here was that handedness plays no role in the outcome of 7 m shots at the world-class level, but handedness does appear to play a role in who becomes a world-class 7 m shooter. © 2022 by the authors.

- The purpose of this study was to examine the relationship between legal stops and winning in team handball. Real-time analysis was performed on all games played in the Icelandic elite division for both males and females (regular season and playoffs) between 2017–2021 (854 games [570 male games, 284 female games], 32,392 legal stops in total). Legal stops were assessed as any physical action by a defensive player that resulted in the stop of play, without the defensive player being penalized or the offensive player receiving a 7-meter throw. The results from a multinomial logistic regression analysis indicated that legal stops were significantly associated with winning games in the male league. No statistically significant relationship was found between illegal stops and game outcome for either sex. However, 2-minute suspensions were found to be positively associated with winning in the male league. © The Author(s) 2022.

FIDES Athlete Development Programme : project background and study protocol of an embedded multiple case study

Tidskriftsartikel (refereegranskat)abstract
- Most sports science research revolves around male subjects. As a result, most of the knowledge and practices within sports are male-centric. Failing to take the biological, psychological and social (biopsychosocial) particularities of females into account is believed to hinder optimal sports participation, development and performance, with potential negative effects on the health and well-being of females. To close the knowledge gap and alleviate these issues, we aim to develop and evaluate a 12-video educational intervention that addresses female-specific subject matter: the FIDES Athlete Development Programme. The study is designed as an embedded multiple case study where at least 1320 Swedish female athletes aged 13-16 will participate, in addition to their parents and their coaches. The girls will be recruited through their sports clubs, with half being exposed to the FIDES Athlete Development Programme and the other half serving as control cases. The primary outcomes are well-being and sporting experience. To further increase our understanding of the intervention and its implications, interviews and focus group interviews with a reference group of girls and focus group interviews with a randomly selected subsample of coaches and parents will also be performed. The project is approved by the Swedish ethics committee (number: 2023-05264-01) and will be carried out in compliance with the Declaration of Helsinki. Results from the project will be published open access in peer-reviewed journals, at national and international conferences, in mass media, and a PhD thesis. The anonymised data will be made openly available in a data repository.

- Research on the ergogenic effects of music on athletic performance usually includes multiple antecedents simultaneously. Consequently, this study set out to isolate a single antecedent using a highly controlled experiment. More specifically, the aim of the study was to investigate the effect of pre-task, slow- and fast-tempo music on arousal, affective state, perceived exertion, and anaerobic rowing performance by isolating music tempo as the sole intrinsic musical factor. Forty young adults (male = 23, female = 17) participated in three trials where they all were exposed to no-music, slow-tempo, and fast-tempo music conditions in a randomized order. The music was exclusively composed for this study and equally novel for all participants. It was based on the same electronic track with a techno-orientation rendered to both 110 (slow-tempo) and 140 (fast-tempo) BPM. Following music exposure, the participants were momentarily asked to report levels of felt arousal and affective state before being instructed to perform a 30-s maximal rowing test on an ergometer. Upon completion of each rowing test, subjects were then asked to report their perceived exertion. Both fast- and slow-tempo pre-task music exposure led to increased arousal and positive affective state when compared to no music. Fast-tempo music led to a significantly higher mean power output than slow-tempo music. No significant differences were found for peak watt output or rating of perceived exertion when comparing all conditions. These findings suggest that exposure to pre-task music may offer positive psychological benefits prior to commencing anaerobic sporting tasks. Results also suggest that fast-tempo music may have an ergogenic effect on anaerobic performance. © The Author(s) 2023.
